Title: Versatile gardening tool
Inventor: DUNGEY STANLEY
IPC: A01B1/02
Filed: 1986-09-06
Abstract: Traditional garden hand-tools have not altered basically since their introduction. The tool of the present application enables several everyday operations to be performed with one tool. The ergonomically shaped handle, set at rightangles to the blade, enables the same handhold to be used for all the operations, and the wrists can be turned through 90 degrees to left or right so that spoil may be deposited to either side with equal facility. The rounded tip to the handle is convenient for the use of tool at any required angle, and the extra long shaft makes for increased leverage and less back bending. <IMAGE>

Title: Valve for power assisted steering
Inventor: ADAMS FREDERICK JOHN
IPC: B62D5/08
Filed: 1986-10-18
Abstract: A fluid valve, comprises a housing 1 having a fluid pressure inlet port 6 leading to a first fluid pressure chamber 7, first and second closure members in the form of balls 4 and 5 with co-operating respective seats located within, and closing respective outlets from, said first chamber 7. First and second mutually opposed slide valves 24 and 25 operating in a common second fluid pressure chamber 23 have resilient means 26 for urging the slide valves apart. The outlets from the first chamber 7 communicate respectively with the mutually remote ends of the slide valves 24 and 25 and that part of the second chamber 23 between the slide valves having an outlet 33 to drain. The side valves 24 and 25 each alternatively effect communication between a respective final outlet port 36 or 39 and either the remote end of the slide valve or the drain 33. The rod 8 is centralised by spring 11 and extends to outside the housing 1 to be connected to the arm of a vehicle steering mechanism in known manner. Movement of the rod in one direction or the other causes pressure fluid to flow to one side or the other of a fluid ram assisting steering, returning fluid entering the valve and passing to the outlet at drain 33. <IMAGE>

Title: Process for the continuous impregnation of nonwoven or needle felt webs with an activating solution for electroless plating
Inventor: KISTRUP DR HOLGER
IPC: C23C18/28
Filed: 1987-09-07
Abstract: Webs having a thickness between 1 and 10 mm and a porosity between 50% and 97% are continuously impregnated by spraying or immersion with a noble metal containing activating solution for the purpose of subsequent metallisation, in the web being impregnated with the activating solution with a forward feed speed of 1 to 10 m/min and the contact time of the web with fresh activating solution is at most 120 min. Since the further treatment of the impregnated web (rinsing processes etc.) can likewise be carried out with the same speed, the process makes it possible to construct a continuous activating station where, starting from a roll, an activated roll is produced as end product without the continuous operation having to be interrupted even once.

Patent GB-2234868-A (GB)
Title: Simplified electronic starter for fluorescent lamps
Inventor: MARTIN DAVID JOHN
IPC: H05B41/04
Filed: 1989-07-20
Abstract: A starting pulse is generated each time a fluoractor F turns off when the voltage on a capacitor CI reaches a level sufficient to turn on a transistor TR2 diverting triggering current away from fluoractor gate G. and after a predetermined time triggering current flow in resistor R1 is diverted before it reaches a level sufficient to trigger fluoractor F so that pulsing stops. In this state transistor TR2 acts as a linear amplifier in a control loop which regulates the voltage on capacitor CI to be just sufficient to maintain the diversion of triggering current. This minimises the discharge time of capacitor CI thus reducing the period for which the circuit must be held deenergised before it can generate starting pulses again. The control loop includes resistors (Rb); (Ra). (Figs 11, 12), connected internally of fluoractor F between its gate G and cathode K. If the circuit is connected across the lamp via a half wave rectifier D1 it is operable in each positive half cycle of the mains supply to produce multiple starting pulses, or only one pulse followed by oscillation if a capacitor C2 is omitted (Figs 10A, B). A full wave rectifier bridge may be used instead of rectifier D1. <IMAGE>

Title: Liquid, powder, or heavier gas dispenser
Inventor: HALLAM JOHN EDWARD
IPC: G01F11/28
Filed: 1990-07-20
Abstract: The dispenser needs no moving parts to reliably provide pre-determined doses of dispensate (11) to a receiving substance (12). The incentive for injecting the dose may be a simple fall in the level of the receiving substance, or a forced pressure difference. Vents may be provided to improve operational efficiency, or safety.

Title: Optical time domain reflectometer
Inventor: SHIPLEY SIMON PAUL
IPC: H04B10/071
Filed: 1993-01-29
Abstract: An optical signal transmission network comprises a main optical fibre having a plurality of branch circuits, with each final branch circuit of a chain of branches ending in a terminal unit, and the network being associated with OTDR equipment connected so as to transmit an output signal through the main fibre and the branch circuits, wherein each said final branch circuit incorporates a filter which is capable of reflecting back towards the OTDR equipment at least one wavelength in the OTDR band, but not traffic wavelengths. The filters may be located immediately before the terminal units, and may be switchable between reflective and transmissive states for OTDR radiation, whilst transmitting traffic always: if they are switched sequentially, this allows the branch to be identified by examining reflected pulses. Alternatively the filters may be in a spur, in which case they may transmit or alternate traffic. <IMAGE>

Patent GB-2276753-A (GB)
Title: Recording method and system
Inventor: TOZER EDWIN PAUL
IPC: G11B27/034
Filed: 1993-04-02
Abstract: Source material is recorded on a recording medium by playing (12) the source material in a first pass, deriving (18) a control signal responsive to a parameter of the played source material, processing (16) the source material in a second pass for adjusting the parameter of the played source material in accordance with the control signal and recording (14) the processed source material on a recording medium. For recording digital signals on a recording medium, for example for optical disc mastering, a maximum digital recording level value (e.g. for an optical disc) is prestored and then a control signal is derived by determining a digital source parameter value corresponding the maximum signal level from the complete first pass of the source material, then determining a scaling control signal in dependence upon the relative values of the digital recording reference parameter value and the digital source parameter value. The source material played during the second pass is then linearly scaled in accordance with the scaling control signal and the linearly scaled digital signals are recorded on the optical disc. This enables the full range of digital values and/or the full dynamic range of the recording medium to be exploited. The various steps can be controlled automatically by a sequence controller (20). <IMAGE>
